What is Wireless mesh?

Wireless Mesh is terminology used to describe a wireless data network. What makes Mesh Networks so appealing is their ability to be deployed in all types of environments. Mesh Networks are commonly found supporting voice, data, and video. Municipal links commonly support video surveillence application throughout a community. The advantage of a Wireless Mesh Network is that it uses wireless switching that routes data via the path of greatest efficiency ala Ohm. A disadvantage of wireline networks is that they are vulnerable to a single point of failure. Wireless Mesh Networks are comprised of nodes that may support access points or simply data transmission. Vehicles may also act as nodes when equipped with an embedded node. Vehicles may also be used to extend a network. If a tornado takes out a node, you simply dispatch a node equipped vehicle to take its place. Also, when a node goes down, data is switched around it, keeping the network up.


Wireline logging engineer?

Responsible for a vehicle-mounted data survey unit making wireline log measurements in boreholes for clients in the coal, mining, water and geotechnical industries. The logging technique involves data acquisition from a variety of electronic probes that are lowered into a borehole using a vehicle mounted electric winch. The probes measure the physical parameters of the rock continuously throughout the borehole and transmit it to a data recorder on the surface. These measurements can be interpreted as types of rock type, fluid properties and mechanical properties

What is the difference between noise-domain reflectometry and time-domain reflectometry?

Time-Domain Reflectometry works by generating a signal and then sending that signal down the wireline and examining the reflected signal to ascertain wire faults. Noise-domain reflectometry does not introduce an external signal to test the wire, but examines the existing signals already on the wire to locate those faults. Wikipedia has a number of good descriptions on TDR and variaions of TDR. See the links below.


What is the difference between LWD and MWD?

MWD is measurement while drilling. It records values like direction, inclination, toolface etc, which all are values needed to achieve a successful drilling. LWD is logging while drilling. It records logs (which generally are run by wireline, after drilling). Most common being gamma and resistivity logs. It gives us real time log data which helps to geosteer. In BHA, the arrangement is like... [ BIT - RSS* - MWD* - LWD* ] (* - optional)


What is bromine trifluoride used for?

In the oil & Gas industry Bromine Trifluoride is used as the main agent on a device called a "Chemical Cutter" Which is used to cut sections of piping inside an oil well. This is used by lowering said tool with Electric Line or "Wireline" and the tool pushes the chemical through a mesh filled with mineral oil making making it react to achieve high temperatures and then shoots the reacting chemical towards the pipe which then "melts it" in a radial fashion so that part of the stuck pipe can be recovered


What s the perforation service in the oil field?

A perforating service is the act of perforating holes thru the steel caseing, thru the cement used to secure and seal the caseing to the earth, and out into the oil or gas producing zone. Perforating a well uses a wireline truck which contains a large spool of wire line or cable. Inside the wireline or cable are electrical wires that are used to run special equipment on board the truck to locate the oil zone. After the zone is located, this same wire line is used to lower the "perforating gun" into the caseing and locate it properly. After the proper location is established the electrical wires are used to detonate explosive charges that do the actual perforating of the caseing,cement and oil zone. These "perforations" or holes, are where the oil or gas enter the caseing to be produced at the surface. Usually the same company that dose the perforating of an oil well, will have other services that use the same cable, spool and electrical wireing. These services are known as "logging" and consist of electronic equipment that help the oil man determine if the well has penetrated an oil or gas zone. Measurements such as thickness, oil or water content of the zone, percent of permability etc. can be determined from these verious logs.


What is the toll-free number to find out your long distant company?

In North America (USA, Canada, etc.), in most cases you can dial 1-700-555-4141 to find out your default long distance company. There is no charge for calls to this specific number, but other 1-700 numbers may carry premium charges comparable to 900 numbers. Also, if you use a long distance reseller (a company that buys wholesale service from a wireline carrier and then bills the retail customers), you may need to use a different number provided by the reseller.

What is GSM?

GSM is a technology which is the leading cell phone standard all over the world. In 1982 it was recognized as a standard for digital wireless communications and was first adopted in Europe and then by Asia, Africa etc. The first system was online in 1991 and GSM was formerly known as Group Special Mobile but now stands for Global System for Mobile communications. USA, however has not adopted GSM as a standard and so different carriers now use different technologies as opposed to only GSM. GSM uses digital technology and the methods of time division multiple access transmission. In GSM, sound is digitally prearranged through a special encoder, which imitates the distinctiveness of human speech. This method of transmission allows a very competent statistics speed/information content ratio. GSM is an open system and is a non propriety technology. One of the great benefits of GSM is that it facilitates international roaming. As it is adopted by more than 170 countries, you have the facility of using your GSM cell phone in all these places without having to change your number. GSM satellite roaming has broadened the scope of cellular services even to areas where standard terrestrial services are not possible. GSM is a technology that is rapidly growing and constantly evolving with wireless, satellite and cordless systems offering greatly expanded services. These services include multimedia data services, high speed, inbuilt support for side by side use of these services and faultless incorporation with the Internet and wireline networks. 3GSM (next generation of mobile communications services) is already charted out and will make available services enhancing the already existing voice, data, and text services. GSM will provide video on demand and will help to lessen the gap between wireless and internet/computers. GSM works on different frequency bands across the world. In North America it uses a 1900 MHz frequency whereas in other parts of the world it uses either 900MHz or 1800 MHz. As different frequencies are used in different places, your GSM handset should support various bands so that it can be used globally. From the beginning, GSM has been developed with the need to give its customers utmost security in terms of secure communications, fraud prevention, and call privacy. Today it is the worlds most secure public wireless standard for cellular phones. In an entirely different context, GSM could also stand for grams per square metre. This is the standard measure used for paper, and fabrics.


What is optical access network?

Rapidly increasing traffic demands of current residential and business applications and newly evolving services require access network solutions that can offer dramatically higher bandwidth. New applications tend to be media-rich such as high-definition television (HDTV), video on demand (VoD), voice over IP (VoIP), and high-speed Internet. Emerging applications include multimedia conferencing, multiplayer online gaming, online content generation, and consumer-oriented cloudcomputing solutions, and are even more demanding and bandwidth-hungry. As a result, future wireline access networks will be faced with the challenge of transporting the ever increasing volume of data-centric traffic with ever tighter timing and quality of service (QoS) requirements.
